Distinguishing Quantum Capacitance Signatures of a Topological Majorana Wire from a Normal Wire Segment
Binayyak Bhusan Roy, Jay Deep Sau, Sumanta Tewari
Majorana zero modes (MZMs) are spatially separated, near-zero-energy excitations expected at the ends of a topological superconducting (TS) wire. A quantum-dot interferometer can b…

Quantum Inductance as a Phase-Sensitive Probe of Fermion Parity Switching in Majorana Nanowires
Binayyak B. Roy, Jay D. Sau, Sumanta Tewari
We study the flux-dependent quantum inductance of a one-dimensional (1D) semiconductor-superconductor (SM-SC) Majorana nanowire coupled to a quantum dot in an interferometric setup…

Dynamically Robust Counterdiabatic Topological Pumping
Joshua Chiel, Christopher Jarzynski, Jay Sau
Thouless pumping is a transport phenomenon whereby an insulating, time-periodic Hamiltonian induces a robustly quantized transfer of charge, per driving cycle, in the quasi-adiabat…
